AgentGuards setup

Guide the user through finishing AgentGuards setup after installing the plugin. The plugin already bundles the MCP server and the enforcing hooks — the only thing the user must supply is their API key.

Steps

Check for the API key. Look for the AGENTGUARDS_API_KEY environment variable. If it is missing or does not start with ag_, tell the user to:
- Get a key from the dashboard at https://agentguards.co/dashboard/keys
- Export it so both the MCP server and the hooks can read it. For the current shell and future sessions, add to their shell profile (~/.bashrc, ~/.zshrc, etc.):
```
export AGENTGUARDS_API_KEY=ag_your_token_here
```
- Restart Codex (or start a new session) so the MCP server and hooks pick up the key from the environment.
Confirm the URL (optional). AgentGuards defaults to https://prod.agentguards.co. Only set AGENTGUARDS_URL if the user runs a self-hosted instance.
Fail-open vs fail-closed. The hooks fail closed by default — if the AgentGuards service is unreachable, actions are blocked. A user who prefers availability over strict enforcement can set AGENTGUARDS_FAIL_OPEN=true. Mention this only if they ask or report unexpected blocks.
Verify. Call the AgentGuards health_check tool from the agentguards MCP server. Report whether the service is reachable and which key prefix is active. If it fails, the most common cause is AGENTGUARDS_API_KEY not being exported in the environment Codex was launched from.
Summarize what is now active: UserPromptSubmit input scanning, PreToolUse shell-command authorization, PostToolUse web-content scanning, and the check_input / authorize_action MCP tools.
